Design a sophisticated Canva graphic template that features a pristine white background, exuding a modern and airy elegance, perfectly complemented by beautifully illustrated fruits like vibrant yellow pineapples and deep blue blueberries. Incorporate a blank text box in a sleek triangular shape, characterized by smooth, unobtrusive borders that blend seamlessly with the overall design while serving as a prominent focal point. This triangular text box should be strategically positioned to enhance the layout without disrupting the flow of the surrounding elements. Carefully arrange the fruit illustrations around the text box, creating a balanced composition that draws the viewer's attention while ensuring a professional appearance. The template should be tailored for social media graphics, providing clear visual guidance for users on where to insert their text, resulting in a polished and engaging design ready for immediate use.
